I think Hurly Engineering sells them, but they are $20K+.
I'm making one this summer out of half a 12A. Going to have a machine shop cut down the eccentric shaft.

Check out Hayes Engineering, or possibly Atkins Rotary. I am not sure which one is doing it, but one of them makes a single rotor engine. They also make marine engines, and are researching rotaries for military use.

What applications are you considering for the engine? Go-Kart? Riding Lawnmower?
Either way, fill me in!

The NSU Spider (world's first production rotary car) had one, as did the Suzuki RE5 motorbike, but I'm pretty sure that's it for production vehicles. Mazda actually supplied a few single rotor versions of their motors (called 6A and 7A) for NASA to use in target drones years ago. But the best one I've seen is the single rotor Curtiss-Wright developed in the 60's to power large pumps and generators. It had a capacity of 1920ci or 31.5L and made 782hp @ 1525rpm!

Here's a photo of the rotor out of that 1920ci engine. The other rotors are other developmental engines, one a bit bigger than a 13B, the other about half the size.

And here's a photo of the world's smallest rotary engine, made by O.S. Engines inJapn for model aircraft. It's just 5cc and makes an amazing 1.27hp @ 17,000rpm, that's 254hp/litre! It's 70mm in diameter and fits in you hand. I've seen a photo of one in a RC car, but apparently the power made it undriveable!

Am i the only one who looked at the rotor housing of the model engine and wondered "those ports are so tiny, I don't have a Dremel bit small enough to port them"?

I think it would be cool to make a single rotor say 13b size and then p port it and put it in a shifter super cart. you could make at least a 100 hp and it would be small and light weight and mabe a little bit fast too. hehaaea.

I've seen ultra lights with single rotor motors, but i don't know where they came from. this was before i had an interest. Funny sounding....like one hand drumming
